Hello
Welcome to HCM
According to history provided your kid most probably suffering from acute gastro
enteritis.
Gastro enteritis presents with vomiting, loose motions ,
abdominal pain and signs of infection like fever.
Major concern is hydration of your baby. You already told that your kid is receiving IV fluids so it will take care of your baby.
Secondly your baby is unable to take oral medications then appropriate
IV antibiotic with antiemetic is essential to take care of infection.
Please pay attention on urine output of baby or any altered sensorium.
baseline investigations are important like serum electrolyte,
complete blood count, stool examination with culture to decide about appropriate antibiotic.
Please visit near by general physician or
pediatrician for proper management of your baby.
Hope I have cleared your query
Regards
